atmRmonDataCollectMode
Cisco ATM Rmon Data Collect Mode
1.3.6.1.4.1.9.10.16.1.5.1
Controls the internal data collection for the entire ATM-RMON agent. If this object has a value of 'active(1)', then data tables will be created and maintained (normal behavior). If this object has a value of 'inactive(2)' then ATM-RMON monitoring will not occur, even if valid control tables exist for particular collections. Data tables for active collections are deleted when this object is changed to 'inactive(2)', but control tables are not deleted. When this object is changed to 'active(1)', data collection is started for all valid control tables.
